Battery drained next morning after DQ Track Instal

We had our DQ Track unit installed on the Friday of the 5th of June 2015. The very next morning our vehicles Battery was totally drained, without us using the vehicle at all from the time of the installation to the next morning, apart from moving it back to the one side of the garage.<br> I phone in immediately (on Saturday) and am told that they don't work on weekends except for emergencies. (I can't use my car, which evidently does not bother them or constitute an emergency, then I don't know what is)<br> On Monday morning first thing, I phoned in to have them sort out this mess and then I'm asked all kinds of questions about my battery!!! With every effort being made to blame the battery!!! Which I never had problems with before, but the very next day after installation, they want to point fingers at my battery!!! First of DQ Track could only give me an appointment for Wednesday, then while I was telling the lady that Wednesday is unacceptable someone else apparently booked Wednesday and I'm told I can now only have Thursday!!!! How do I get around, earn a living or get my kids to school in the meanwhile!!!??? You can cancel my Insurance if this is not sorted by the end of today!!!
